This article begins with an overview of biological development based upon empirical research. The main focus of the article is the presentation of the major theoretical frameworks that have been employed to explain the processes involved in the psychological, cognitive, moral, social, and sexual development of the adolescent and empirical research findings where appropriate.

This entry begins with a presentation of demographic data from the U.S. Census 2010 on the adolescent population 12 to 19 years by age, gender, and ethnicity. A summary of the information available on major issues and problems affecting adolescent populations is presented from numerous governmental and empirical research sources on the following topics: education, runaway and homeless youth, sexual behavior, substance abuse, suicide, victimization and criminal behavior, and texting while driving.
Rates of depression increase during adolescence and may put youth at risk for suicidality, future episodes, and impaired functioning in multiple life domains. Increased vulnerability for depression during this stage may occur because it is when the cognitive capacity for personal reflection, abstract reasoning, and formal operational thought develop; depressive styles for attributing events may hence form, along with hopelessness about the future. However, other biological and social influences may also interact with the increased cognitive vulnerability. Latino ethnicity and female gender appear to exert particular influence. Treatment for adolescent depression includes medication (mainly Prozac and Zoloft), cognitive-behavioral therapy, interpersonal therapy, and family therapy. Medication and psychosocial treatment is also combined, particularly for treatment-resistant depression.
